I'm having huge issues with the new editor and resizing images to what they used to be. I had a series of icons on one page; now I have a series of forcibly larger images. Et voila:

How do I resolve this? I can't see any other way to manage the image size other than through these bar thingies they've added on the side. I'm really hoping Atlassian isn't just now mandating how large things can be.
It's such a pain, because the page got a lot of good feedback, and now it looks like a bag of balls.
